Not trying to be an *** like someone else in this thread... but you can't add up how much power each mod is supposed to get you. Those are individual numbers. When you start combining mods you get less. With all those mods listed, you probably gained 40rwhp. You really don't need tuning either, not after just headers. You might get another 5rwhp.
